- 1inch’s launch on Solana brings MEV-protected swaps, open-source contracts, and intent-based trading to a growing network.
- With Solana’s high transaction volume and speed, 1inch aims to bridge cross-chain liquidity and enhance DeFi efficiency.
1inch, the decentralized trading aggregator established in May 2019, has moved a step ahead by rolling out its offerings on Solana and infusing much-needed cross-chain plans into its pipeline. This move puts Solana in the ambit of 1inch’s Fusion protocol that plans to reform decentralized trading with the emphasis on optimizing liquidity and slippage management.
This launch brings users on Solana in touch with six developer APIs, MEV-secured onchain trades, and 1inch’s open-source smart contracts. The Fusion protocol operates in a Dutch auction mechanism that has market makers bid against user trade requests. The protocol tries to achieve optimisation of price by initiating the rate high and reducing it gradually to the point where the trade is performed.
The model takes advantage of intent-based trading, in which users set what they want to do — i.e., a particular token swap — and professional market makers referred to as resolvers execute these requests. It is a structure that is intended to decrease price inefficiencies and achieve better outcomes for end users.
Solana’s Q1 Surge Sets the Stage
Solana’s performance in the decentralized finance world has gained substantial momentum in 2025. During the first quarter alone, the network recorded a 33% higher decentralized exchange volume — totaling $539 billion — compared to Ethereum and its layer-2 counterparts. According to data from Dune Analytics and DefiLlama, Solana also managed to process 400% more transactions and drew 180% more active addresses.
As one of the fastest-growing ecosystems in the blockchain space, Solana’s increased usage and adoption have made it an appealing platform for protocols like 1inch, which is looking to extend its cross-network reach. A 1inch representative noted, “Both Solana and Ethereum play critical roles in the evolving DeFi landscape,” pointing to Solana’s improved performance metrics and growing user base.
While Ethereum continues to lead in liquidity depth and network effects, Solana’s speed and efficiency give it the potential to compete closely in the DeFi arena. This backdrop has provided a strong foundation for 1inch to bring its solutions to Solana users.
Bridging Chains, Building the Future
Looking ahead, 1inch is planning to introduce cross-chain swaps between Solana and ten other networks it already supports. The objective is to bridge liquidity gaps across blockchains and unify what has long been a fragmented DeFi environment. This strategic vision aligns with 1inch’s earlier moves, including its debut on the Ethereum scaling solution Optimism in 2021 and Base in August 2023.
The groundwork for this cross-chain functionality began on September 12, 2024, when 1inch unveiled a white paper outlining its intent-based, cross-chain interoperability protocol. Just six days later, on September 18, 2024, the team introduced “Fusion+” — a feature that enables digital asset swaps across blockchains while maintaining self-custody of those assets.
Sergej Kunz, 1inch’s co-founder, commented, “Our integration with Solana moves us closer to uniting disparate chains,” emphasizing the broader goal of connecting isolated blockchain ecosystems. With these developments, 1inch is positioning itself to offer seamless asset movement without compromising user control or decentralization.
